At 26? Gosh yes.
At 26 I don't know any one of my circle of friends - post uni, working, partying hard, city living - who would have replied anything other than 'God I don't know! Can't imagine having a baby haha!'
Fast forward a decade and they'd all started or were trying to start families.
If you were 35 saying this I'd answer differently.
He's 34? What will quite probably happen to him is that he'll come round to the idea by 40, because he has the luxury of choice, and quite possibly find a younger woman to have babies with. Or... he really might not. You don't gamble your fertile years on that, no.
The advice I would give, being utterly practical, is to not waste time with a man in this category because if/when you do change your mind at 32, and if you're still with him, you're back to square one, harder to move on, and more of the good guys are taken.
So I'd end it now and move on.
